With the Wondercore’s revolutionary Dual-resistance design, your muscles are firing throughout the entire range of motion, on the way down as well as on the way up! You’re doing a reverse crunch against resistance as you lie back and a regular crunch as you come up. And unlike Ab machines in the gym that work through a limited range of motion, Wondercore can go beyond 180 degrees with an extended range of motion to target your core like never before! With its adjustable resistance – anyone can do it!

Its unique ergonomic design focuses the resistance on your upper, middle, lower abs and your oblique’s, so there’s no wasted effort or wasted time! It even has a built in twisting seat so you can target your oblique’s. Wondercore is an incredible "6 in 1” Total Core workout machine,
